Research opportunities

More and more of the images in our lives are being digitally captured, copied, shared and printed. Yet most images typically need to undergo an enormous amount of processing as they are created and used.

HP has a long history in printing and imaging, and has built up a considerable portfolio of innovations in this area.

HP Labs is making major contributions to that portfolio -- driven by the vision of doing nothing less than helping people create perfect pictures every time.

Research focus

We are developing better image-processing technologies for improved image quality, designing easier-to-use imaging devices and reducing the costs of producing great pictures.

Current work

Much of our research focuses on image enhancement based on image content. By detecting the presence of people, for example, one can improve how they look by automatically adjusting the color balance and contrast of their skin tones.

Once an image is captured, this type of analysis has further applications. Knowing where the people are in a picture, for example, enables auto-cropping of an image to make a better-looking picture.

Image analysis also contributes to HP's media management solutions, which help people sort through their image libraries and automatically create engaging slideshows or other presentations. (See related information on photo and video collection management research.)

Another of interest involves turning raw sensor data into the best possible image inside a still or video camera. Similar problems need to be addressed in printers, where processing is required to convert a digital picture to printer dots.

In addition to these efforts, we are working with a group of technology, nonprofit and governmental organizations from around the world to build a permanent archive of multilingual digitized text and multimedia content.

As part of that group -- the Open Content Alliance -- HP Labs is contributing technologies to process scanned books and quickly create enhanced, compressed PDF files .

Technical contributions

Much of our work in image analysis and processing has been applied to HP cameras, printers and scanners, as well as to Snapfish, HP's online photo-sharing and printing serviced. These solutions include:

  • image sharpening
  • improved color reproduction
  • image 'noise' reduction
  • in-camera redeye (and 'pet-eye') correction
  • in-camera panorama stitching
  • adaptive lighting
  • improved image compression
  • resolution synthesis for improved image scaling in printers
  • adaptive demosaicing to better estimate missing color information from sensor to image
  • dust and scratch removal
  • artifact removal
  • out-of-focus detection

Our expertise in image and video processing has also been leveraged to solve professional content-processing problems such as automating film restoration.
